Specification of Letters Patent. Patented July 18, 1911.

Application filed April 23, 1910. Serial No. 557,254.

- it toadjust itself to slight inequalities in the wire without jumping therefrom, and to so mount the wheel that the bearings thereof will be protected frommain, snow and ice;

and also from dust.

The invention consists in the novel con struction of the trolley wheel support and means for mounting same upon the trolley poll; substantially as illustrated in the accompanying drawings and described and cxplained with reference thereto.

In the drawings-Figure 1 represents a front view of my novel trolley wheel support connected to a pole. Fig. 2 is a vertical longitudinal section therethrough. Fig. 3 is a section on the line 34 looking upward, showing the lugs on the under side of the trolley head. Fig. i is a transverse section on the line 8-4 looking downward, showing the lugs on the support.

piece ,1 having a cylindric body, and provided onits upper end with opposite arms 1 between which is mounted the shaft 1- of the trolley wheel 9. The shaft and wheel may be of any desired construction. Said cap-piece l is provided with an internal transverse partition or head 1 which is prometrically opposite, lu'gs 1; and the cylindrical ortion of the cap-piece 1 extends be low thisflange 1, forming a skirt-flange 1" for a purpose hereinafter stated.

Connected centrally to the head if is a. shank-member 3, which is preferably made of a section of pipe united to a central opening in the head by a threaded joint, as shown at 3, or in any other suitable manner; andthi's shank fits freely within a tub11134. supporting member 5, which may also be a section of pipe slightly larger the nut 3 The device, as shown, comprises a ca'p-' inclosed by the cap-piece 1, head l bearing plate 4, and flange 1',

in diameter than the shank 3, and is provided on its upper end with an annular flange-or hearing plate 4-, which may be formed separately from the tubular member 5 and be secured thereto by a threaded joint-as shown at 4, or in any otherconvenient mannen The bearing plate 4 is adapted to fit neatly within the flange 1 of the cap-piece l and under the head 1*; and said bearing plate 4 has on its upper side, preferably diametrically opposite, lugs 4 which are adapted to engage the under side of the head 1 intermediate the lugs 1. It will be seen that by this arrangement the and at the same time limit the rotative movement of the cap-piece on the support 5, the amount of rotative movement of the cappiece upon the support being regulated by the number and" width of the lugs 1,

lugs 1?, 4, practically- .support the cap-piece upon the member 5 something over degrees of rotative movement being allowed the cap-piece in the construction shown.

The tubular shank with the support 5 b as shown an annular the lower end of the shank slightly beyond the lower end of the'support 5. The support 5 is adapted to be attached to a trolley pole P in any: suitable way; but as shown is provided on its lower end with an internally threaded nipple which is fastened to the lower end of the support 5 and extends below and surrounds and is internally threaded so that it can be screwed onto the upper threaded end of the trolley pole Pwhich canoe out to the desired length and threaded to en gage the nipple 7', see Figs. 1 and2. .It will seen that the hearing parts are entirely Y any suitable means;

3 which projects protected from dust, rain, snow and ice; while the trolley wheel may at all times readily accommodate itself to slight lateral bends and in inequalities of the trolleywires as is desirable with high speed cars. W'hat I claim is: A trolley head comprising a tubular support adapted to be attached to-the end of a trolley. pole and having an annular bearing plate on its upper end, saidplate having opposite segmental shaped lugs'on its upper face; a hollow cylindric body rotatably surrounding said bearing plate and projecting both above and below the same and having 3 is rotatably confined and are effectually' nut 3 is screwed on an internal partition above the bearing plate, said partition having opposite segmental shaped lugs on its under side alternating with those on the said bearing plate said lugs supporting the body upon the bearing plate 'and also limiting the relative rotatory movement of said body and plate; a tubular shank extending througlrthe said support and bearing plate and having its upper end fixedly attached to said partition, means on the lower end of said shank to con fine it against longitudinal motion in the support While permitting its turning with the body; and a trolley Wheel mounted on said body above the said partition, substantially as described.

In testimony that I claim the foregoing my own, I. aziix my signature in presence of two Witnesses. 7
